Mode oe feeding and pressing straw in straw-cutting machines



ATET @FICE MODE OF FEEDING AND PRESSING STRAW IN STRAW-CUTTING MACHINES.

Specification of Letters Patent No. 1,573, dated April 30, 1840.

T0 all whom i?? may concern Be it known that I, ISRAEL 1V. Gnorr, ofLampeter township, in the county of Lan caster and State ofPennsylvania, have invented a new and useful Improvement for CuttingStraw, Corn-Fcdder, &c.; and I do hereby declare that the following is afull and exact description.

A box is made in the common form about six feet in length ten incheswide, and about eight inches deep, andplaced on a frame of sufficientheight; see No. 1. An iron shaft of about three feet long, an inch and ahalf in diameter, called the fly wheel shaft (A) is placed on the offside of the box. The pedestal (B) in which the fore end of the shaftturns is made fast near the top of the off front foot in such a positionthat the shaft will be about opposite the center of the box in height,and about six inches from the side of it. On the front end of this shaftis placed the fly wheel (C) which is made of metal about forty inches indiameter, with a bar dividing it in two equal segments, these segmentsare subdivided by two arms running from the middle of the periphery, andeach joining the first mentioned bar about three inches in front of thecenter, and to the arms are attached the cutters These cutters are madeabout thirteen inches long, and three broad;

about three-fourths of an inch of the back of these cutters extend twoand a half inches longer than the blade, and are bent at right angleswith the blade, which forms the means by which they are fastened to thearms. A elutch-bolt, is put through the arms holding each of thesefastenings, and is made fast by a screw and nut on the other side (Gr)On the opposite end of the fly wheel shaft is placed a bevel wheel (H.)of about eight inches in diameter, working in a similar bevel wheel,(I.). On the end of a shaft, which passes at right angles with theformer shaft under the box, and both resting on a pedestal, (J fixed onthe frame of the box, this may be called the crank shaft, (K.) or theshaft by which the whole is put in motion; the other end of this shaftalso rests on a pedestal, fixed on the frame which supports the box.Close to the side of the box, on this shaft is placed two cams, one ofwhich, (M.) works against 'a lever, (N.) to which is attached a dog,

(O.) which works the upper feed roller. The other cam, (m.) operates ona lever, (P.) on the opposite side of the shaft, and to which isattached a rodk (Q.) that works the bearer, (It) The bearer is a blockof wood of about two and a half inches thick in front, and about fourinches broad, and in length to suit the inside of the width of the box.This block is somewhat beveled in front, leaving the lower side longest,and rounded at the bottom, the back edge about one inch thick with asmall tenon on each` which frame extends down, and is joined under thebox, and from it on each side immediately below the shaft a branch,(lV.) extends backward alongside of the box about two feet in length,the hind end of which is fastened to the side of the box by a pivot, Inthis part of the frame, about two inches behind the bearer shaft, is ashaft on which is placed a fluted, or ribbed roller, about four, or fourand a half inches in diameter, called the feeder, (Y) And also on thenear end is placed a rack wheel, of about the saine diameter in whichthe dog,O,heretofo1ie described works. The fore end of this fra-mecontaining the bearing shaft and feeder, is movable upward and downward,to suit it to the quantity of straw or fodder in the box. To the lowerpart of this frame is attached the end of a spiral spring, 6a.). Theother end of this spring extends downward and is attached to the framesupporting the box. This spring by its contraction assists the pressureof the bearer. to this wheel (a) to prevent it from receding while theother is drawn back. Near the hind end of the first mentioned doganother dog (c) is attached by a pivot, which works a similar rack wheel(d.) and a roller (e.) made like the one heretofore described.

An additional dog is putr The shaft of this rack Wheel and roller is lplaced under the box, so that the roller extendsup in the box a smalldistance above the surface of the bottom, and with the other rollerforms the feeder. A spiral spring (f.) is fastened to about the middleof the branch, (W) on the near side, and also to the dog (O.) Whichsupports, and `holds it to its place on the rack Wheel. A movable stop l(i) is placed on the side of the box, at the top of lever (N.) for thepurpose of regulatng the feeder. The two levers are drawn toward eachother by a spiral springnear their lower ends. Y

No. `l, is the machine, or box in perspective; No. 2, the opposite sideof the box; No. 3, front View of the fly Wheel.

Vwhich the dogs are'worked by the cams, the

feeding by this operation being,` made thicker or thinner, and the stuffcut short or long at pleasure.
